README

A PHP SDK for the SoundCloud Public API, built on Saloon.

Installation

composer require stanislavhannes/soundcloud

Authentication

SoundCloud supports two OAuth 2.1 flows. Which one you need depends on whether you want to access public data only or a specific user's private data.

Flow	Access	`Me` resource works?
Client Credentials	Public resources only	❌ No
Authorization Code	User's private data	✅ Yes

Client Credentials

Use this for accessing public resources (tracks, playlists, public user profiles, search, URL resolution). The SDK automatically fetches an OAuth token and refreshes it when it expires (~1 hour).

Important: SoundCloud requires credentials to be sent as an HTTP Basic Auth header (Authorization: Basic Base64(client_id:client_secret)), not as form body fields. This SDK handles that automatically.

Important: The Me resource (/me/* endpoints) returns 401 Unauthorized with a client credentials token. These endpoints require a user-level token obtained via the Authorization Code flow. If you want to access your own followings, feed, likes etc., use the Users resource with your numeric user ID instead:
// Resolve your profile URL to get your numeric user ID
$userId = $client->miscellaneous()->resolveUrl('https://soundcloud.com/your-username')->json('id');

// Then use the public Users resource
$followings = $client->users()->userFollowings($userId, 200);

use Stanislavhannes\Soundcloud\Soundcloud;

$client = new Soundcloud();
$client->authenticateWithClientCredentials('YOUR_CLIENT_ID', 'YOUR_CLIENT_SECRET');

// All subsequent calls are automatically authenticated
$track = $client->tracks()->getTrack(123456789);

Authorization Code (OAuth 2.1 + PKCE)

Use this when you need to access or act on behalf of a specific user — their private tracks, feed, followings, likes, etc. This requires the user to log in via SoundCloud's connect screen. PKCE is required.

Once you have the user's access token, pass it directly:

use Stanislavhannes\Soundcloud\Soundcloud;
use Saloon\Http\Auth\TokenAuthenticator;

$client = new Soundcloud();
$client->authenticate(new TokenAuthenticator('USER_ACCESS_TOKEN'));

// Me resource now works
$profile   = $client->me()->userInfo();
$followings = $client->me()->userFollowings(50, null);

See the SoundCloud API guide for how to implement the full redirect + PKCE + token exchange flow.

Manual Token

If you already have an access token from any source:

use Stanislavhannes\Soundcloud\Soundcloud;
use Saloon\Http\Auth\TokenAuthenticator;

$client = new Soundcloud();
$client->authenticate(new TokenAuthenticator('YOUR_ACCESS_TOKEN'));

Internal Mode

SoundCloud's unofficial api-v2.soundcloud.com endpoint allows broader access using only a client_id. Useful for read-only use cases without user authentication.

use Stanislavhannes\Soundcloud\Soundcloud;

$client = new Soundcloud();
$client->enableInternalMode('YOUR_CLIENT_ID');

$track = $client->tracks()->getTrack(123456789);

$client->reposts()->repostPlaylist($playlistId);
$client->reposts()->removePlaylistRepost($playlistId);

OAuth

// Fetch a token manually using client credentials
$response = $client->oauth()->clientCredentials($clientId, $clientSecret);
